1 Claim.

This invention, broadly considered, aims to provide novel means for removing odors from a closet bowl. The invention aims, further, to supply a novel suction means, together with mechanism actuated by a toilet bowl cover for rendering the suction means active When the cover is opened, and inactive when the cover is closed.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other cbjects in view, which will appear as the description proceeds, the invention resides in the combinaticn and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings:

Fig. 1 shows in top plan, a device constructed in accordance with the invention;

Fig. 2 is a Vertical section on the line 2-2 of Fig. 1;

Fig. 3 is a vertical section on the line 3-3 of Fig. 1;

Fig. 4 is a vertical section showing the parts as they will appear when the cover or lid is closed;

Fig. 5 is a similar view showing the parts as they will appear when the cover or lid is opened.

The numeral l marks a closet bowl. Curved hangers 2 are detachably mounted on the bowl. The hangers 2 have annular feet 3, cooperating with the upper surface of the bowl. The hangers 2 carry a shaft 4. The numeral 5 designates a toilet seat. By means of hinge members 6, the seat 5 is mounted on the shaft 4 to swing vertically. A cover or lid is shown at l. By means of hinge members 8, the cover 1 is mounted on the shaft 4 to swing vertically. The hinge members may be considered as parts of the cover 1.

The numeral 9 marks a suction intake member. The suction intake member 9 tapers as it extends forwardly, to form a mouth lil. The intake member 9 is placed on top of the bowl I, and the bowl closes the bottom of the intake member, as shown best in Figs. 4 and 5. The intake member 9 extends orwardly to a place close to the periphery of the seat 5. At its ends, the intake member 9 has fianges ll, which extend underneath the feet 3 of the hangers 2, and, thus,

the intake member 9 is held in place on the bowl I.

At any appropriate place is located an electrically operated suction device l2. A conduit M leads from one end of the intake member 9 to the suction device z.

The intake member 9 is provided with an internal bearing !5. A horizontal shait !3 is journaled in the hearing 15 and in the adjacent end wall of the intake member 9. EXternally of the intake member 9, a crank arm l'l is secured to the shaft !6 by any appropriate means !8. The rear end of a link l9 is pivoted at 28 to the crank arm 11. The forward end of the link !9 is pivoted at 2! to one of the hinge members a of the cover 1.

A cylindrical switch housing 22 is secured to the inner end of the shaft [5 and is provided with a removable end closure 23. The end closure 23 has a central hole 2 t. A container 25 is held against the outer end wall of the housing 22 by a compression spring 26, nterposed between the container and the end closure 23. The container 25 holds a quantity of mercury 21. The container 25 is supplied with spaced contacts 28. To each contact 28, a conductor 29 is electrically secured. The conductors 29 are enclosed in a sheath 30, extended outwardly through the hole 24 in the closure 23, and through the conduit !4, to the electrically operated suction device l2. The sheath 30, it will be noted, is completely hidden from View.

Noting Fig. 4, when the cover 'I is closed, the mercury 21 is spaced from the contacts 28, the circuit of the suction deVi-ce l2 is opened, and no suction is produced at the mouth [ll of the intake member 9.

Referring to Fig. 5, when the cover 1 is opened, the link !9, Operating by way of the crank arm l'l, rotates the shaft !6. The mercury 21 moves into engagement with the contacts 29, the circuit of the suction device [2 is closed, and suction is produced at the mouth lfl of the intake member 9, to draw away odors within the bowl l.

The closure 23 and the spring 26 must be disassociated from the housing 22, when it becomes necessary to renew the mercury switch. The closure 23 and the spring 33 can be slid to the left, in Fig. 3, along the conductor sheath 38, and will not drop into the bowl I.

What is claimed is:

In an odor evacuator, a toilet bowl, a cover mounted to swing with respect to the bowl, an electrically operated suction device, an elongated intake member mounted on the bowl in operative relation thereto, a conduit leading ;from the intake member to the suction device, a. shaft journaled in one end of the intake member, a switch housing mounted at one end on the shaft and disposed within the intake member, a removable closure for the opposite end of the housing and having an opening, a mercury switch within the housing, a compression spring engaging the closure and the switch and retainng the switch against said one end of the housing, means for 10 Operating the shaft from the cover, and a circut including the switch and the suction device, the circuit comprising a, part which passes through a portion of the spring and through the opening and retains the spring and the closure, to prevent them from dropping into the bowl, When the closure is removed for the renewal of the switch.
